This invention relates to a combined shearing and bending machine forlath metal.

It is an object of the present invention to provide a combined shearingand bending machine by which straps of large sheet material can be cutand while upon the same pass of the large sheet material the cut strapswill be bent into angle section.

Other objects of the present invention are to provide a combinedshearing and bending machine which can be fabricated from stock piecesof material, which will be compact, easy to construct and assemble, andefficient in operation.

For a better understanding of the invention reference may be had to thefollowing detailed description taken in connection 'with theaccompanying drawing, in which Fig. 1 is a top plan view of my shearingand bending machine,

Fig. 2 is a front elevation view of the machine looking upon the cuttingand crimping rolls,

Fig. 3 is a rear elevational view looking upon the drive connections tothe roll shafts,

Fig. 4 is an end elevational view of the machine looking at the end ofthe same which has the crimping or bending rolls,

Fig. 5 is a transverse cross-sectional view taken on line 5-5 of Fig. 2and looking in the direction of the arrows thereof,

Fig, 6 is a cross-sectional view, in elevation, taken on line @-5 ofFig. 2 and looking in the direction of the arrows thereof and throughthe crimping or bending rolls,

Fig. 7 is a fragmentary cross-sectional View taken upon one of thethreaded posts and as viewed on line 'I-l of Fig. 1 and looking in thedirection of the arrows thereof,

Fig. 8 is a cross-sectional View, in elevation, taken on line 8-8 ofFig. 1 and looking in the direction of the arrows thereof and throughthe cutting roll shaft housings,

Fig. 9 is a cross-sectional view taken through one of the bearings andthe top crimping roll shaft and as viewed on line 9-9 of Fig. 1,

Fig. 10 is a fragmentary and detailed crosssectional view taken throughthe guide plate on the table and as viewed on line I-I of Fig. 1 andlooking in the direction of the arrows thereof.

Referring now to the Jrigures, I5 represents a base plate from whichthere is extended upwardly to the cutting roll side of the same fourposts I6 which are threaded into the base as shown at I'l, Fig. 8. Uponthese posts I5 there is mounted a spacing block I8, a plate I9, a lowercutting shaft housing 2|, plates 22 and 23, upper cutting roll housing24 and a top plate 25. All of these parts are secured tightly to thebase by a clamping washer 25 and a nut 2l on each of the posts I5.

Extending through the housing 2I is a lower cutting roll shaft 2Smounted in ball bearing elements 29 at opposite ends of the housing 2Iand having extensions 3I and 32 extending from the opposite ends of thesame. On the extensions 3| is a feed roll 33 vhaving a rubber ringportion 34. Also on the extension 3l is a lower cutting roll 35. Theserolls are secured upon the extension by a clamping nut 36. On the otherextension 32 is a gear 3l, a sprocket 38 and a drive coupling element39. These parts are retained upon the ex.. tension by a nut 4 I.

In the upper housing 24 is upper cutting roll shaft 42 journalled inball bearing elements 43 in opposite ends of the housing, Fig. 5. Thisshaft has at opposite ends of the same extensions 44 and 45. On theextension 44 is a feed roll 45 having its rubber ring portion 41engaging with the rubber ring portion 34 of the feed roll 33. Also uponthe extension 44 is upper cutting roll 48 cooperating with the lowercutting roll 35 to effect a shearing action of any sheet materialextended between these cutting rolls. A nut 45 retains the upper feedroll and the cutting roll 48 upon the extension 44.

On the extension 45 is a driving gear 5I meshing with the gear 3l of thelower cutter shaft 23 so as to be driven thereby and to cause therotation of the cutting roll 43. There is also on the extension asprocket 52 and the gear 5I and the sprocket 52 are retained uponextension against axial displacement by a clamping nut 53. A key 54fixes the gear 5I and the sprocket 52 to the extension 45 againstrotational displacement. A similar key 55 is provided on extension 44for the feed roller 46 and the cutter 48. Likewise the part on theextensions of shaft 28 are keyed thereto.

Plate 23 serves as a table on which the sheet material is extended whenpassing the same through the cutting rolls 35 and 48. This plate 23 issupported externally of the housings 2| and 24 by a, verticallyextending plate 55 which may be welded to the same and to the base I5.In the plate 23 are elongated slots 5l through which bolts 58 may extendfor clamping the angle guide 6I in any of its adjusted positions. Thesheet material is rested upon the table top or plate 23 and slid towardthe cutting rolls 35 and 48 and upon being engaged by the feed rolls 33and 46 will be drawn into the machine. Metal laths will be cut anywherefrom a small fraction of an inch 3. to six inches depending on thelateral adjustment of the guide or gauge 6|.

The severed metal lath will automatically pass to top and bottomcrimping or bending rolls 62 and G3. The top roll 62 is keyed asindicated at S4 to a shaft 65 journalled in bearing brackets 66 and 67,Fig. 6, secured by bolts 68 to top plate 25. On the opposite end of theshaft 65 there is fixed a sprocket 69 which is connected by a chain H tosprocket 52 of the cutter roll shaft 42 so that the crimping roll shaft65 will be driven by the same.

To the plate I9 there is connected bearing brackets 72 and 13 throughwhich extends a lower crimping roll shaft 'M having the crimping roll 63thereon. A key 75 fixes the roll 63 upon the shaft 'ld against rotationrelative thereto. On the opposite end of the shaft there is fixed asprocket 77 which is connected by a lower chain 18 to sprocket 38 of thelower cutting roll shaft 28. It will thus be seen that power isdelivered to the crimping or bending rolls 62 and 63 by means of chains'H and 78.

Plate 22 extends laterally from the cutting roll housings 2l and 24 tosupport the severed lath upon being passed through the crimping orbending rolls 62 and 63. The plates E9, 22 and 25 are all supported onthe output end of the machine by threaded posts 8l and 62. These postshave threads extending throughout their entire heights and the platescan be adjusted along them by turning upper and lower retaining nuts 83and 84. Spring washers 65 may be disposed between the nuts 33 and 64.

Within the plates I9 and 25 which support the lower and upper bearingrolls there are provided at their connection with the post i6 elongatedslots 86. This will permit the plates to be laterally adjusted so as torelease the chains 7l and 78 or permit the connection of the chains withthe sprockets. The bearing brackets for the crimping roll shafts may beconnected at different distances from the mounting plates by replacingshim plates 87 disposed between the brackets and the plates. By usingshims of different thicknesses diiTerent size and shape crimping rolls62 and 63 can be used.

While various changes may be made in the detailed construction it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as dei-ined by the appended claim.
